Definitions

  • This invention relates generally to housings for accommodating electrical equipment adapted to be served by one or more electric cables originating externally of the housing and admitted from outside of to inside the housing to there terminate and be electrically coupled to said equipment when installed. More particularly, this invention relates to housings of such kind having upper and lower entry ways to facilitate admission of such one or more cables into the housing, when they originally lie above and below it, respectively.
  • Housings of the son described are designed to be installed in rooms in which the one or more cables which terminate in the housing may approach it either from above the housing (as, say, in ducts above the ceiling of the room) or from below the housing (as, say, in ducts below the room's floor). Since it is often not possible to predict in advance whether a particular housing will be installed in a room where the cable or cables to end at the housing will approach it from above or below, it has been a common practice to have housings of two different designs to meet those two contingencies.
  • past housings have commonly been either of a first design having only an upper entry way for admitting a cable approaching from above, and extending down into the housing to a free end or, alternatively, of a second design having only a lower entry way for admitting a cable approaching the housing from below and extending upwardly into the housing to a free end.
  • Housings of either the first design or the second design have included as a feature a cable receptor connector to which the free end of the admitted cable was mechanically coupled in order to electrically couple the cable to equipment in the housings.
  • a cable receptor connector to which the free end of the admitted cable was mechanically coupled in order to electrically couple the cable to equipment in the housings.
  • Such receptor connector differed, however, for the two designs in that, in housing with upper entry ways and lower entry ways, respectively, the connector from its support extended vertically upwards and downwards, respectively, in the first and second of such designs.
  • housings for equipment having both upper and lower entry ways in the same housing to adapt it to have a cable approaching the housing from either above or below admitted into through, respectively, the upper entry way or the lower entry way, and by providing in the housing a receptor connector and means in the housing permitting the free end of the admitted cable to be electrically coupled to that receptor connector without undue bending of the cable whether admitted through the upper entry or the lower entry way.
  • FIG. 1 is a left side elevation of apparatus according to the invention comprising a housing and racks therein for accommodating electrical equipment;
  • FIG. 2 is an enlarged broken-away front elevation view of the FIG. 2 housing showing the top rack in that housing;
  • FIG. 3 is an enlarged broken-away left side elevation in cross section, taken as indicated by the arrows 3--3 in FIG. 2, of part of the top rack and of associated extension cables and adjustable support means for the front ends of such cables, such means having been adjusted so that those front ends point upwards;
  • FIG. 4 is an enlarged left side elevation, taken as indicated by the arrows 4--4 in FIG. 2, of the FIG. 3 extension cables and support means therefor when such means is adjusted to cause the front ends of such cables to point downwards;
  • FIG. 5 is an enlarged front elevation of the FIG. 3 extension cables and support means therefor when such support means is in its position shown in FIG. 3;
  • FIG. 6 is a plan view in cross-section, taken as indicated by the arrows 6--6 in FIG. 5, of the FIG. 3 extension cables and support means therefor.
  • the reference numeral 9 designates apparatus which is an exemplary embodiment of the invention, and which comprises a housing comprising a vertically upstanding framework 10.
  • Such framework is of rectangular shape both in horizontal cross- section and in vertical cross-section both laterally and longitudinally.
  • the framework has a top 11, a bottom 12 and vertically extending sides disposed between such top and bottom and consisting of longitudinally- spaced front and back sides 13 and 14 (FIG. 1 ) and left and right sides 15 and 16 (FIG. 2) laterally spaced from each other.
  • a pair of laterally spaced feet 17, 18 raise framework 10 above the floor on which it rests.
  • the structure of the framework comprises four upright posts at its four corners. Three of such posts 21, 22, and 23 are shown in FIG. 1 and/or FIG. 2 while the other post 24 is hidden from view.
  • the vertical posts 21 and 22 at the left side 15 of the framework are coupled together by vertically spaced horizontal longitudinally extending braces 26a-26d while a similar set of braces 27a-27d (of which braces 27a and 27d are shown) couple the posts 23, 24 at the right side 16 of the framework.
  • the posts 22, 23 are coupled together by a set of four vertically spaced horizontal laterally extending braces similar to the braces 26a-26d and 27a-27d, but of which only two braces 28a, 28d of these four laterally extending braces are shown in FIGS. 1 and 2, the others being broken away (FIG. 1).
  • a similar set of four vertically spaced horizontal laterally extending braces couples together the posts 21 and 24 at the back side 14 of framework 10, two posts 29a, 29d of the four last braces being shown (FIGS. 1 and 2) while the remaining two posts are hidden from view (FIG. 1 ) or broken away (FIG. 2). All the braces described above are fixedly joined at their ends to the posts coupled thereby to provide a rigid structure by the framework 10.
  • the sides 13-16 of framework 10 are disposed around an interior space 30 thereof which, if desired, may be further enclosed by panels which are parts in addition to the framework of the mentioned housing and which are fastenable to the sides of the framework to provide enclosures for space 30.
  • Two such panels 31 and 32 (FIG. 1) are fastenable to the front and back 13 and 14 of framework 10 to be carried thereby, and two other panels (not shown) are similarly fastenable to the left and right sides 15 and 16 of framework 10 to close in space 30 on those sides.
  • top braces 26a-29a and bottom braces 26d-29d of framework 10 form two horizontal rectangular frames extending at the top 11 and bottom 12 of the framework around rectangular openings therein providing upper and lower entry ways 35 and 36, respectively, for the framework's interior space 30. While some of the area of those entry ways may be covered by screening (not shown), each of entry way 35 and 36 has at least a portion thereof which is adjacent to the left side 15 of framework 10, and which provides an unobstructed opening to the interior space 30.
  • FIG. 1 shows three such cables 37a, 37b and 37c, and a further large cable 37d, passing from above housing 10 and through entry way 35 from outside of to inside housing 10 so as to position in space 30 lengths 38a, 38b, 38c 38d of those cables terminating in respective coaxial end couplings 39a, 39b, 39c and 39d at the free ends of such cables.

  • the longitudinal extent of passageway 50 is coextensive with that of the space itself (FIG. 1 ) whereas, in the lateral direction, the extent of passageway 50 is (FIG. 2) limited by the presence in space 30 of container means 45, the result being that the longitudinal extent of passageway 50 is greater than its lateral extent.
  • the container means 45 consists of a vertical plurality of racks 55a, 55b, 55c each adapted to hold in housing 10 equipment installed therein. Since all of such racks are similar in size, shape and function, only rack 55a will be described in detail.
